A space planner is responsible for diagramming how an interior space should be organized to create an optimal balance of space and utility. This includes planning room layouts to optimally arrange furniture, equipment, telecommunications and other needs. Space planners work in a variety of settings, typically commercial or industrial, such as office buildings, classrooms, research facilities, and centralized computer facilities. They often work in conjunction with interior designers and architects to create plans that make the most efficient use of space.
